* gtk/gtkclist.[ch]:
	* gtk/gtkctree.c:
	When there is a row highlighted for D'n'D it must alse
	be painted hightlighted on exposes. Otherwise exposes from
	the icon being dragged will mess up the hightlight.

	* gtk/gtkfontsel.c:
	Don't recenter selected font when exposing the font family
	clist. This means you can now actually scroll the font family
	list.

	* gtk/gtknotebook.c:
	Fix focus movement on scrolling tabs that are placed on the left
	and right.
